Linux phones try to build from upstream Linux, and the major phone SoC vendors HATE upstreaming their code.
They believe every character in their source code is absolutely top secret.
A middle ground I wish was considered more is taking Google's kernel and the vendors DLKM partition/DTB/DTBO for hardware support, and putting a GNU userspace on top.
This has had problems in the past, because vendors would modify syscall tables such that they don't match userspace anymore, but with GKI, I think we're closer to that being a possibility
Thats always the problem with building hardware open source products. You spend millions developing the OS to work with your stuff and you get like six months before someone else is competing with you, except they didn't have to spend that investment. The only reason we got the steamdeck was because the guys that made it ALSO owned the means of putting games on it, so they didn't really need to make money on the product itself (kinda like with Google and the play store).
At least with the vendors I'm referring to (2/3 that make all Android phones), they just took the open source code, hacked it up as quickly as possible to get some basic drivers working, and moved on.
There wasn't any "special sauce" in the source, they just didn't want to spend the effort to upstream it
Edit: Just because you said "hardware open source" I wasn't advocating for open hardware, just for hardware vendors to, ya know, support the hardware
